Framework and Underpasses

In parallel with prefabricated arches, Adhorna has a series of lower rectangular passages. This is a perfect complement since it permits covering almost the entire buried structure.

Furthermore, advantages that prefabricated structures offer in comparison to on-site structures are fabrication and setting into operation speeds as well as aesthetic finishing, cost control, and quality.

Depending on the section of the passage and land coverage, we can adopt different types of passages.

Framework

Generally used with medium and low beams, and with the possibility of being carried out based on the same, in one or several parts. There is potential for isostatic or hyperstatic actions.

Porches

They cover the large section passage field with up to 15 m beams and with varying heights, in several parts, with on-site foundations and pier caps.
